SPECIFICATION forming part of Letters Patent No. 459,512, datedSeptember 15, 1891. Application filed January 7, 1891- Serial No.376,965- (No model.)

To all whom it may concern.-

Be it known that I, ANSON PARKER MER- RILL, of Fall River, in the countyof Bristol and State of Massachusetts, have invented 5 certain new anduseful Improvements in Shutter-Fasteners; and I do hereby declare thatthe following is a full, clear, and exact description of theinvention,w'hich will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

This invention relates to certain improvements in shutter or doorfasteners.

The object of theinvention is to provide an improved automaticfastenerexceedingly simple in construction, thorough, effective, andautomatic in action, composed of a minimum number of parts assembled tooperate without the employment of springs, and which will operate tolock the shutter or door easily, whether slammed or swung easily.

These objects are accomplished by and my invention consists in certainnovel features of construction and in combinations of parts more fullydescribed hereinafter, and particularly pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a side elevationshowing a portion of the shutter or blind or door and the sill, thefastener being locked; Figs. 2 and 3, plan views, portions being brokenaway, showing, respectively, the fastening device open and the fasteningdevice closed. Fig. 4 is a detail perspective of one of theeccentricallypivoted swinging operating dogs or blocks.

In the drawings, reference-letter 0 indicates the door or shutter, 19the sill, and c the pin or book carried by the sill or the wall of thehouse to lock the shutter or door closed or open. The fastener isdoublethat is, it is so formed as to automatically lock the shuttereither closed or open against the wall of the house.

(Z is the double-pivoted catch or hook of the fastener extending throughand projecting from both sides of the shutter and at its opposite endshaving the oppositely-extending shoulders e e and beveled, as shown.This double-swinging hook is pivoted at or about the center of itslength at b in the metal box f, secured in the rabbeted out portion inthe under edge of the shutter. This box is open at both sides, as shown.The shank of the swinging hook is provided with a pair of shoulders 71.,located on opposite sides and a distance from the pivotal point of thehook that is, the shank atits center is enlargedlaterally-and theseshoulders are form ed by the diagonally-opposite ends of this enlargedportion, whereby each shoulder h is located opposite the engaging orlooking shoulder at its respective end of the shank. These shoulders hare preferably rounded to form bearing-surfaces. The pair of blocks ordogs 2' are pivoted in the box, and extend, respectively, to oppositeopen sides thereof. Each block has an extended inner end provided with apair of lateral pintles j on opposite 7o sides thereof and integraltherewith, fitting in openings in the sides of the box to form journalson which the dog can swing. Outwardly from said pivotal point each dogis enlarged laterally and inwardly, and is provided with the roundedinwardly-extending shoulder 70, bearing against the shoulder 71, of thelocking-hook. The outer end of each dog, located opposite its respectiveshoulderof the hook and a sufficient distance therefromto receive thestationary pin or hook, is preferably cutoff square, as clearly shown.Each locking shoulder or end of the hook is provided with one of theseeccentrically-pivoted operating-dogs,

so that whenthe blind moves in either direc- 8 5 tion toward one of thestationary pins or hooks before mentioned the outer edge of thelocking-dog will come in contact with said pin, and will thereby beswung inwardly on. its pivot, and its bearing-shoulder 76 will bear 0against and press shoulder h of the lockinghook and will swing said hookso as to catch said pin between hook and block, thereby locking theblind quickly and easily and noiselessly. It will be readily seen that ablind or shutter will not have to slain or shut very hard or hard enoughto be heard in the house before it would catch and if it should swingvery hard it would catch just the same.

It will also be seen that the interposition roo consisting of thelaterally-swinging hook having the lateral shoulder on one side of itspivotal point, and the laterally-swingin g eccentrically-pivoted doghaving a lateral shoulder engaging said shoulder of the hook and havingits outer edge adjacent to and located a short distance from theengaging portion of the hook and arranged to operate as set forth.

2. The combination, in a shutter-fastener, of the metal box, the doublehook extending therethrough and pivoted therein and having oppositebearing-shoulders on each side of its pivotal point, and the twoseparate eccentrically-pivoted dogs located in opposite sides of saidbox and arranged, as set forth, to operate as described, and each havinga lateral bearing-shoulder to bear on one of said shoulders of the hook,as set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two Witnesses.
